in step 4 and in the dashboard. I have enter the access id and key manual as well as copy and paste. I have regenerated and access id and key and still having the same problem. What do I need to do?

I am not sure what is going on. I set the account up and click the the active link in my email. It is working now. I guess I had to wait a little for it to active on there system. The program is giving me Blank stats now. It is not giving me information on page ranks or information about my pages
